Support modifying the plot style by introducing a generic framework for overriding components #4914

What

Part of UI for overriding SeriesStyle in TimeSeriesViews #4817

This tackles the problem of allowing SeriesStyle components to be overridden by building out a significant chunk of a general component override framework.

The new UI is limited to TimeSeriesScalar view at the moment because it still requires special Visualizer-side handling of the component data.

High level idea

When selecting an entity within a space-view, we now have the ability to override any component that is both queried by the visualizer, and for which we have a registered component-editor.

This override value is initialized based on looking for, in order:

The current value of the component for the entity
A value provided by the Visualizer (useful for things like matching the current auto-color)
A default value provided by a function registered along with the editor.

Notable changes:

Adds a new mechanism to the Component UI Registry that allows us to register editors and default-value providers for any component.
Adds a mechanism to all visualizers to find out the full set of components they query.
During the update_overrides process, we now checks the appropriate location in the blueprint override tree and insert the path to any overridden components into the DataResult.
In the TimeSeriesSpaceView we now respect any overrides that come from the DataResult.
Introduce a new Override Components UI in the seleciton panel, which allows us to add an override using a default-provided, or visualizer-provided initial value.
Once the override has been added, the override UI dispatches to the registered editor for each overridden component.

absolutely marvelous and not as complex as I feared it would be.

Comments are mostly starts of discussions, some of which we should have over Zoom or Slack instead, some of which need to be postponed.
The only thing that I believe is actually wrong is how initial overrides are determined (see comments). But since this won't affect the time series space view, I'll approve anyways (:

+fn edit_color_ui(
+    ctx: &ViewerContext<'_>,
+    ui: &mut egui::Ui,
+    _verbosity: UiVerbosity,


I wonder if ui verbosity ever makes sense for editors. Aren't they always only available at full verbosity?

I think it will eventually. I suspect there will be both a Small/Inline editor for some things, when it's appropriate, but I could imagine a way of expanding that to a more "full" multiline editor that we won't always want to show in the selection panel by default.

+                    let arr = c.to_array();
+                    egui::Color32::from_rgba_unmultiplied(arr[0], arr[1], arr[2], arr[3])
+                });
+
+                let override_label =
+                    lookup_override::<Text>(data_result, ctx).map(|t| t.to_string());
+
+                let override_scattered =
+                    lookup_override::<ScalarScattering>(data_result, ctx).map(|s| s.0);
+
+                let override_radius = lookup_override::<Radius>(data_result, ctx).map(|r| r.0);


let's discuss after this PR how we can make this pattern nice, easy and fast. Overall doesn't look as bad as I thought it would (:

Yeah, it's not awful, esp since we restrict things to splats at the moment, but I'd still love to have it automagically happen inside one of the archetype-view-style generic queries.

this doesn't check out for me: The system for the initial value may not have brought up the component that we're on right now.
I think what you iterate instead is pairs of component-visualizer where you somehow removed duplicated components, i.e. decided which visualizer would provide the initial override value :/

Aha! Yes, good catch. Changed to build a map of Component -> Visualizer and use the right now.

+                };
+
+                initial_data.compute_size_bytes();


why is this needed?

🤷 it's always needed when we write data to the store or else we get errors about using data that hasn't been sized yet.
